Producing the required magnitude and shape of reference current is necessary to achieve precise torque control in motor control applications. A deadbeat predictive current controller provides very good dynamic performance. In order to achieve very accurate reference current production the machine and inverter should be modeled properly with accurate parameters. Parameter changes, especially the back...
This paper describes a fast torque control system of permanent magnet synchronous motor (PMSM) based on model predictive control (MPC) considering overmodulation region of inverter. In overmodulation region, output voltage of inverter contains harmonic voltage which influences performance of current control and can't be avoided. To consider influences of harmonic voltage, we use a harmonic voltage...
In this paper, torque control scheme for PMSM when an inverter operates in the overmodulation range is proposed and examined. The torque control system has our proposed closed-loop current control system, which harmonic current compensation scheme is used to improve the stability in the overmodulation range. Finally, the overall torque control performance will be evaluated by the experimental results.
In the wind energy conversion system, the wind turbine captures the wind energy. Then the generator changes it to the electrical power. So the characteristic of the wind turbine is very important. For some laboratories that donpsilat have the practical wind turbine, it is very convenience to use the wind turbine simulator instead of the real wind turbine. The paper introduces the structure and characteristic...
